<br />Boring Log Preparation <br />The subsurface conditions encountered during drilling are reported on a field log recorded by <br />the chief driller. The driller's field record contains information concerning the boring method, <br />samples attempted and recovered, indications of the presence of various materials such as <br />coarse gravel, cobbles, etc., and observations between samples. Therefore, these records <br />contain both factual and interpretive information. The field logs are on file in our office. <br />The soil samples, plus the field logs, are reviewed by a geotechnical engineer, geologist, or <br />geotechnician. The engineer/geologist/geotechnician then classifies the soil in general <br />accordance with the Unified Soil Classification System and prepares the final boring logs, which <br />are the basis for our evaluations and recommendations. The group symbol for each soil type is <br />indicated in parentheses following the soil descriptions on the boring logs. The final boring logs <br />represent our interpretation of the contents of the field logs based on the results of the <br />engineering review and laboratory testing of the field samples. The final boring logs are <br />included in this section.
